A diss track made by Ice Cube aimed at his former band mates from N.W.A. and their manger, Jerry Heller. After shots where taken at him in the songs "100 Miles and Runnin'" "Real Niggaz" "A Message to B.A" and "Alwayz Into Somthin". The song samples the first 7 seconds, and the baseline of the 1970's song "Dazz" for its instrumental. Various lines from the song such as "You lookin' like straight bozos, I saw it comin', that's why I went solo" and "Get rid of that devil real simple, put a bullet in his temple!" has made this track, and "Hit Em' Up" by Tupac widely regarded as the best/strongest diss tracks.
